21, 28, 29, 30, will present a sinuous contour, as

shown in Figures 2, '1, and 9.

Shiftably mounted concentrically within the discharge passage 24 is avalve stem 3| rigidly provided at its upper end with a shouldered poppet32 having an upwardly projecting guide stem 33 extending into the poppetguide-recess II and being normally urged downwardly by means of acompression spring 34 into seated engagement against the upper face ofthe rubber collar 26. At its lower end, the stem 3| projects downwardlybeyond'the discharge passage 24 and is threaded for receiving adownwardly pointedconcentric cone 35, the apex of which is normallylocated just above the plane of the discharge nozzle 23.

' Extending horizontally in and projecting radially outwardly from theside faces of the cone 35, at an angle of approximately 120 to eachother, are three round-ended guide pins 36 adapted to ride looselyagainst the inner face of the nozzle I9 for holding the cone" 35 and itsassociated valve stem 3| in substantially concentric alignment duringupward and downward movement. Upon its upper end face, the cone isprovided with upwardly projecting concentric roundtopped ridges 31, 38,and round-bottomed grooves 39, 48, respectively matching andcomplementarily tting within and around the grooves and ridges 21, 28,29, 30, of the nozzle member I9. Extending vertically through the valvebody I, in spaced parallel relation to the recess 1 and adjacent to thefront end face 5,'is a bore 4I opening at its upper end upon the upperend face 3 and being internally threaded for a short distance downwardlytherefrom to threadedly receive a flat disk-like end plug 42, which iscentrally bored and counter-bored in the provision of a check Valve port43 and a downwardly opening ball socket 44. About midway of the valvebody I, the bore 4| is reduced in diametral size in the provision of ashoulder 45 having a raised annular valve seat 46, and, in eiect,forming a valve chamber 41 within the upper end of the bore 4I. Snuglyfitted within the lower or reduced-size end of the bore 4I forlengthwise shiftable, but leakproof movement therein, is a syrupdischarging spout 48, which, at its upper end, projects upwardly intothe valve chamber 41 and in diametrally enlarged and undercut forreceiving a downwardly presented annular ring washer 49 for seatedengagement against the valve seat 46. Upon its upper end face the spout48 is provided with a slightly raised concentric projection 5|) forvreceiving the lower end of a compression spring 5|, which is, in turn,at its upper end retentively seated against the under side of a smallcheck valve ball 52 operatively disposed within the recess 44 for seatedengagement within the port 43. Directly beneath the region of the ringwasher 49, the spout 48 is turned to a slightly reduced diametral sizeand is provided with a plurality of radially extending orifices 53connecting the interior of the spout 48 with the interior of the valvechamber 41 when the spout 48 is lifted to the position shown in Figure'1.

Opening upon the rear face 6 of the valve body I and extendinghorizontally thereinto, in spaced parallel relation to the bore I5, is abore 54 at its forward end intersecting the side wall of and openinginto the valve chamber 41 and being internally threaded at its rearwardend for receiving a conventional fitting 55 connected to a syrup supplyline 56.

At its lower end, the spout 48 projects downwardly below the bottom Wall2 of the valve body I and terminates in a discharge orifice 51 which isnormally in coplanar alignment with the discharge orice 23 of the nozzlemember I9 when the valve A is in closed position, as shown in Figure 9.

The syrup spout 48, for a short portion of its length entirely withinthe reduced-size portion of the bore 4| and upwardly from the bottomwall 2 of the valve body I, is turned to a somewhat reduced diameter inthe provision of an annular recess or groove 58. In the same region orarea, the valve body I is provided with a transversely extendinghorizontal bore 59 opening at its opposite ends upon the sides faces 4,4', and an intersecting angular bore 6D, the center line of which isapproximately in the same plane as, and at an angle of 120 to, thecenter lines of the pins 36. Snugly and rotatively fitted within thebore 59, in the region of its intersection with the bore 6|), is anactuator pin 6| provided at its inner end with an angularly cut Vflatcam section 62, the latter being located within the com-- mon area ofintersection between the bores 59, 66. Upon the outer end face, the pin6| is flush with the side face 4 of the valve body and is integrallyprovided with an outwardly projecting flatsided attachment boss 63. Alsosnugly and rotatively fitted within the bore 59 and extending inwardlyfrom the side face 4 of the valve body I', is a second actuator pin 64terminating at its inner end just short of the syrup spout 48 and beingprovided with an axially projecting eccentrically located pin-likeprojection 65 adapted to iit within the spout-groove 58. At itsV outerend, the pin 64 is substantially flush with the side face 4 of the valvebody and is integrally provided with a fiat-sided boss 66. Fixed uponthe bosses 63, 66, and secured thereto by fiat-headed retainer screws61, 68, which are threaded axially into the actuator pins 6|, 64,respectively, is a clevis-shaped dispensing handle 69 which extendsoutwardly beyond the front end face 5 of the valve body I and ispreferably provided with an inserted rectangular Bakelite block 10 whichserves as an artistic hand grip or knob and is held in place by atubular sleeve 1| extending between the parallel side arms of theclevisshaped handle 69 and being threaded at its opposite ends forreceiving flat-headed retainer screws 12, 13.

Extending through the angular bore 68 and inserted within the cone 35 isa cone actuating pin 14 which rests upon the upwardly presented flatcamming face of the actuator pin 6I, the bore 60 being finally closed bya threadedly inserted end plug 15.

In actual use, the nozzle member I9 may be threaded upwardly, therebyshifting the nozzle cup I9 upwardly and axially shortening orcompressing the rubber collar 26, causing it to bulge inwardly, as shownin Figure 2, thereby reducing or throttling the size of the dischargepassage to control the rate of flow of carbonated water therethrough.The inward bulging of the rubber collar 26 will also produce aVenturi-like or streamline constriction at the throttling point in' the:valve .so 4.that theflow1-ofycarbonated water through theconstricted.area will .be substantially .non-.turbulent .andthe .gas .contentthereof will notrbelostor .scrubbed out, so to speak. i Y

'1t will thus be .seen-by .a simple manual rotation of the Anozzle .1.8,it is possible to--achieve veri/...accurate adjustment in .this respect.rlvhis particular .adjustment is .unique :andextremely important ina.beverage .dispensing valve 4because the rate of Vflow .ofsyrup is notreadily controllable andwillflowat .a rate, which, for all practicalpurposes, is .fairly yconstant Yfor la .substantial period of time.lherate of flow of the ASyrup will, of course, vary. in proportion to.variations inthe hydrostatic head .of/.the `syrup .contained in the.reservoir or storage tank (not shcwn) ,bu-t, dueto the .relativelyhighviscosity :of-the syrup, the eifectofsuch hydrostatic headisrnotparticularly critical. .Howeven Ithe syrup Ywillflow somewhatlfasterwhenthe storage tank is fullandconseduently Va somewhat .greaterquantity of syrup will, .under such..condition,be .dispensed in a ygiven unit .of time .and a `carbonated drinkfwll have a...greaterproportion .of .flavoring .syrup -than a drink which is `made -Whenthestorage tank is 1 elatively.empty. With .the present beveragedispensingvalve A, .this-variation can4 be very` .quick-7 ly .and Aconvenientlycompensated .by Vthe throt- .tling adjustment ofthe discharge .passage2li. For example',.in the-caseof asocia .fountain or 4`softdrinkldispensing bar equipped with the valve A, wherethesyrup Ystoragetank must be -i-villed every twoor .three days,.it .will merely benecessary vto makea .throttling adjustment once every day or so,.reducing .the .ratetof :flow of the carbonated waterslightly .astherate ofow of-.syrup is reduced. commercial practice at .the ordinarydrug-store, soda fountain, and the like, a customer frequently requeststhat his drink be `made up sweet or dry, that is to say, with eithermore or less than the usual amount of avoring syrup and the sodadispenser can easily comply with suchrequest by a simple twist of thenozzle member I9 without any loss of time or inconvenience. When it isdesired to ldispense a syrupilavored drink, the handle 69 is pusheddownwardly, as shown in Figure '7, rotating the actuator pins 6I, 64,whereupon the camming surface 62 lifts the pin .14, cone 35, `theassociated valve stem 3|, and the poppet 32 to permit the ow ofcarbonated water downwardly through the discharge passage 24 past theconcentric convolutions of the nozzle cup ;'I-9 andthe end face of cone35, downwardly through the nozzle member i9 and outwardly through theorifice thereof. At the same time, the pin-like yprojection 65 of theactuator pin 64 is swung eccentrcally upwardly, lifting the spoutlland-thereby allowing the syrup to flow from the chamber l1 .through theorifices 53, downwardly through the interior of the spout 48, andoutwardly `from the discharge orifice 5'! thereof. The discharging syrupand carbonated water will flow simultaneously downwardly into a glass orotherdrink receptacle and will .be thoroughly intermixed.

When it is desired to dispense unflavored or plain carbonated water, thehandle 69 is shifted upwardly, as shown in Figure 9, rotatingr theactuator pins 6l, 64, in the opposite direction. Inasmuch as the cammingsurface 62 of the actuator vpin 6l is flat, it will lift the pins -14when rotated 'in either direction. Thus, when the handle 69 .is swungupwardly and -the actu.

ator .pin 6I is rotated thereby, the vpins 14 and the associatedAcomponent vparts .of the .carbon.
